Hello:

 

Having recently come into possession of a very clean EAC 1967 build

R-390A, I brought it up with variac and dim bulb tester.

 

While bringing the set up to 115 volts, I notice the dim bulb lights up

very well.

 

My question:  Does the R-390A normally draw heavy current?

 

So far, I do not have any audio.  Also, have replaced the 3TF7 with 

a solid state unit, along with several of the tubes.

 

Any ideas?  Thank you, Tom, ABØJ
